Rapid and flexible pavement repairing material and preparation method thereof
The invention discloses a rapid and flexible pavement repairing material and a preparation method thereof. The rapid and flexible pavement repairing material comprises the following raw materials in parts by weight: 480-505 parts of dead burned magnesium oxide, 170-185 parts of potassium dihydrogen phosphate or ammonium dihydrogen phosphate, 45-50 parts of sodium tetraborate, 10-25 parts of rubber particles, 125-195 parts of machine-made sand or river sand, 15-25 parts of mineral powder or silica fume, 4-5 parts of polyvinyl alcohol fibers and 140-160 parts of water. The particle size of the rubber particles is 1-2.5 mm, the particle size of the machine-made sand or river sand is 0.125-1 mm, and the length of the polyvinyl alcohol fiber is 6 mm. The invention has the advantages of reasonable design, effective improvement of the toughness of the repaired part and the whole body, good crack resistance, strong impact resistance, good wear resistance, short setting time, fast development of early strength, no need of large construction machinery in the pavement repairing process, and fast and convenient construction.
本发明公开了一种快速柔性修补路面材料及其制备方法，包括以下重量份的原料：重烧氧化镁480～505份，磷酸二氢钾或磷酸二氢铵170～185份，四硼酸钠45～50份，橡胶颗粒10～25份，机制砂或河砂125～195份，矿粉或硅灰15～25份，聚乙烯醇纤维4～5份，水140～160份。橡胶颗粒的粒径为1～2.5mm，机制砂或河砂粒径0.125～1mm，聚乙烯醇纤维长度为6mm。本发明设计合理，能够有效提高修补部位与整体韧性、抗裂性能好，抗冲击能力强，耐磨性好，同时凝结时间短早期强度发展迅速，路面修补过程中不需要大型施工机械，施工快速方便。
